It’s pretty safe to say that Blizzard’s Overwatch is this year’s biggest new online game so far. In just one month it’s accrued over 10 million players and has achieved the unthinkable – beating League of Legends as the most played game in South Korean PC gaming cafes.

But increasingly, people are only likely to permit this data to be processed by third parties if they can be sure it’s handled in a safe and secure manner that cannot expose any of their personal information.

For many people, their first experience of software distribution and game server hosting will have been with Valve Corporation. Valve’s Steam platform has become the world’s leading digital distribution outlet for PC games. Launched in 2003, it was originally developed for Windows devices, but is now compatible with OS X and Linux too.
